Gillam’s share of its area codes

Within area code 431, Gillam accounts for only 4 of 571 prefixes (0.7%): the code is dominated by Winnipeg and spread over 146 rate centres. Within area code 204, Gillam accounts for only 1 of 781 prefixes (0.1%): the code is dominated by Winnipeg and spread over 245 rate centres.

Who holds these numbers

MTS Inc. holds the largest share at 2 prefixes, 40.0% of the total, ahead of 3 other carriers. Code by code: in 431, MTS Inc. leads with 1 of 4 prefixes ahead of 3 others; MTS Inc. is the only holder in 204. 1 carrier holds prefixes in every one of Gillam’s 2 area codes, while 3 appear in just one.

Wireless and wireline

2 of Gillam’s 5 prefixes (40.0%) are held by carriers whose registered name marks a wireless business: Bell Mobility and TELUS Mobility. Wireline prefixes still outnumber them, carried by MTS Inc and Bell West Inc. This is a sort by name, not a licence lookup, and a mobile prefix may have been ported to another network since.

How the allocation was built up

Gillam’s dated assignments run from 2013 to 2019. The busiest period was 2015–2019, when 3 prefixes went to 3 carriers. 1 prefixes (20%) carry no date in the register: these are the historic pre-1999 assignments, the wireline bedrock of the rate centre. No prefix has been added since 2020: demand for numbers in Gillam is flat.

Gillam’s oldest prefixes, the ones the register leaves undated, belong to MTS Inc: this carrier made up the landscape before competition arrived. The first dated assignment went to MTS Inc. in 2013. The most recent arrivals are Bell West Inc. (2019), Bell Mobility (2017) and TELUS Mobility (2016), a sign that new carriers are still asking for numbers in Gillam.

Gillam has just 5 prefixes (50,000 numbers): a very small rate centre, typical of a village or rural area served by a single switching office.

MTS Inc. leads with 40.0% of the prefixes, but 3 competitors have set up in Gillam: a market where the incumbent keeps the edge without exclusivity.

Allocation is mature: only 0.0% of the dated prefixes are less than ten years old, most having been handed out in 2015–2019, and 1 prefixes go back to the undated monopoly era. New Gillam numbers mostly come out of blocks that were assigned long ago.

Dialling a Gillam number

Gillam is served by 2 overlaid area codes (431 and 204). A 204 number is no more “out of town” than a 431 one; from abroad, dial +1 and the full ten digits.

The numbering neighbourhood

Gillam shares area codes 431 and 204 with at least 20 other rate centres, including Winnipeg, Brandon, Portage La Prairie, Steinbach, Oakbank, Stonewall, Dauphin and Selkirk. The largest of them, Winnipeg, holds 386 prefixes in 204 and 431; the smallest on the list, The Pas, has just 10.

What a Gillam number tells you

A number attached to Gillam tells you that its prefix was issued to a carrier for this rate centre in Manitoba, most often MTS Inc.. It does not tell you where the handset is today: a subscriber may have ported the number to any of the 4 carriers present here or to a VoIP service usable anywhere. Nor does it tell you who is calling: caller ID can be spoofed, and a Manitoba area code is easy to borrow to look local.

Reading a register entry for Gillam: code 431-285 is recorded for MTS Inc., so every 431-285-XXXX number (10,000 possible) descends from that assignment. “Gillam, Manitoba” there names a rate centre, not a municipality, and several area codes overlay it.
